the answer is opposite for apex users and its true

Every positive number has two square roots. Their absolute values are the same. One is positive and the other is negative.

All positive numbers have two. 0 has only one. Negative numbers have two imaginary roots but no real ones.

Any positive number has two square roots, a positive square root and its negative equivalent. This is because two negatives multiplied together equal a positive. In this instance, sqrt(625) = Â±25 (that is, 25 and -25).

Every number has two square roots ... a positive one and a negative one. Example: +2 and -2 are both square roots of 4, because when you multiply either of them by itself, the answer is 4. The positive square root of a number is the square root that's not negative. The non-negative square root of a number is the positive one.
